Choose the form factor — sheet, rod or tube — then specify virgin or filled grade
Virgin PTFE is 100% pure polytetrafluoroethylene without any additives. It offers the maximum chemical resistance, the widest temperature range and the best dielectric properties of any PTFE grade. Filled PTFE is virgin PTFE compounded with a filler — glass fiber, carbon, graphite, bronze, molybdenum disulfide or PEEK — to improve specific mechanical properties such as creep resistance, compressive strength, thermal conductivity and wear resistance at the cost of some chemical resistance.
As an experienced PTFE sheet, rod and tube manufacturer in China, Kaxite Sealing supplies both virgin and filled grades in all three stock forms — sheet, rod and tube — with factory-direct pricing, custom dimensions and full mill traceability.

Each filler improves specific properties — choose by application demand
15–25%. Improves compressive strength & creep resistance
25%. High load capacity, thermal conductivity, low wear
40–60%. Best thermal conductivity, high load bearing
15%. Lower friction, better thermal conductivity

Choose virgin PTFE when chemical resistance and dielectric strength are the priority, especially for food, pharma and semiconductor service. Choose filled PTFE when the application involves high mechanical load, high pressure, elevated temperature with cyclic loading, or dynamic sealing where creep resistance matters.
Glass fiber for general structural parts. Carbon for high load and thermal conductivity. Bronze for the highest thermal conductivity and load bearing. Graphite for lower friction and better heat dissipation. Send us your medium for a recommendation.
Yes. We cut sheet to any dimension, machine rod to any diameter or length, and cut tube to order. Non-standard sizes are our specialty. Please send your inquiry with a drawing or dimensions.

Yes. See our Expanded PTFE (ePTFE) page for gasket, joint sealant tape and soft sheet options.
PTFE tube (also called PTFE tubing) is a hollow cylindrical product made from virgin or filled polytetrafluoroethylene. It combines near-universal chemical resistance, a working temperature range of −190 °C to +260 °C, one of the lowest friction coefficients of any solid material and FDA food-contact approval. This makes it the standard choice for chemical transfer lines, electrical insulation sleeves, food and pharmaceutical transfer, pneumatic and hydraulic lines, laboratory equipment and vibration-damping applications. Kaxite supplies extruded PTFE tube up to 120 mm outer diameter and moulded tube up to approximately 3000 mm, in virgin PTFE or filled grades (carbon, graphite, glass and other additives).
PTFE rod (also called PTFE round bar or PTFE rod stock) is a solid cylindrical product made from virgin or mechanical grade polytetrafluoroethylene. It has the lowest coefficient of friction of any solid material, equal static and dynamic friction coefficients, no slip-stick behaviour and near-universal chemical resistance. This makes it the standard material for machined seals, valve seats, bearing pads, bushings, insulators and laboratory fixtures. Kaxite supplies PTFE rod from 3/32" to 6" in virgin grade and 3/16" to 2" in mechanical grade — on coil or reel, in straight 1000/2000/3000 mm lengths, or cut to customer-specific lengths. Grounded rod is available where exact diameter and roundness are critical.
PTFE sheet (polytetrafluoroethylene sheet) is a flat plate product made from virgin or filled PTFE resin. It combines near-universal chemical resistance, a working temperature range of −190 °C to +260 °C, one of the lowest friction coefficients of any solid material, FDA and EU10/2011 food-grade approval and flame resistance to UL94V0. PTFE sheet is produced by skiving for thicknesses below 6 mm and by compression moulding above, giving a smooth, dense surface that machines easily into gaskets, seals, bearing pads, liners and insulators. Kaxite supplies PTFE sheet from 1 mm to 150 mm in standard stock size 1200 × 1200 mm, with anti-static, one-side etched and two-side etched options available for specific applications.
